photo -chemical degradation of 2, 4- dichlorophenoxyacetic acid (2, 4-d) in the effluent
background: 2, 4-dichlorophenoxy acetic acid (2, 4-d) is well known as inexpensive herbicides but it can give rise to undesirable pollution. the objective of this investigation was to describe a photo-chemical system for degradation of 2, 4-d. methods: a designed photolytic cell system was used in this study with a 150w or 400w uv lamp. a set of experiments was carried out at ph 1.5, 2.5, 3.5 a...
متن کاملsynthesis of 2-phosphonobutane-1, 2, 4-tricarboxylic acid
2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...
متن کاملSYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
